Table 1. EVAL6229QR pin description
Name Type Function
VS Power supply Hal bridges power supply voltage
PGND Ground Power ground terminal.
VDD Power supply Hall effect sensors pull-up voltage.
H1 Sensor input Single ended hall effect sensor input 1.
H2 Sensor input Single ended hall effect sensor input 2.
H3 Sensor input Single ended hall effect sensor input 3.
SGND Ground Signal ground terminal.
DIAG Open-drain output
Diagnostic pin. When ‘low’, signals an overcurrent or
overtemperature event.
TACHO Open-drain output
Frequency-to-voltage open drain output. Every pulse from H1 pin is
shaped as a fixed and adjustable length pulse.
F/R Logic input Selects the direction of the rotation (‘H’ = CW; ‘L’ = CCW).
EN Logic input/output
Chip enable (active ‘high’). When ‘low’, switches OFF all power
MOSFETs of three half-bridges.
VREF Analog input Current controller reference voltage.
BRAKE Logic input
Brake input pin. When ‘low, switches ON all high-side power
MOSFETs implementing the brake function.
OUT1 Power output Output phase 1.
OUT2 Power output Output phase 2.
OUT3 Power output Output phase 3.
